View Your AWS DeepLens Project Output in the
AWS IoT Console

After a successful project deployment, your deployed AWS DeepLens project starts to
run on your
registered AWS DeepLens device. If the Lambda function of your project uses the AWS
IoT Greengrass SDK
(greengrasssdk) to publish text-based messages to AWS IoT, including
JSON-formatted inference results as is done in all of the AWS DeepLens sample projects,
you can view
such project output using the AWS IoT Core console.

If the inference Lambda function uses the OpenCV
Library (cv2) module to output inference results as video feeds,
you can view the video output using a web browser or connecting to the device directly
a
monitor, mouse and keyboard. However, viewing text-based project output is more economical
to verify that your deployed project runs as expected.

To view your AWS DeepLens project out in the AWS Management Console for AWS IoT Core

Open the AWS DeepLens console and make sure to choose the US N.
Virginia region.

From the Device details page of selected device, copy the
MQTT topic value, of the
$aws/things/deeplens_<uuid>/infer
format. You will need to paste this AWS IoT topic ID in the AWS IoT console that you'll
open next.

Inspect the display of the results that your inference Lambda function publishes by
calling the greengrasssdk.publish method. The following AWS IoT console
display shows example results published by the Cat-and-dog-recognition sample
project function:
